1Results are posted according to the sample analysis completion date.2FSIS test results for the 6 target non-O157 STECs appear for only samples of beef manufacturing trimmings from cattle slaughtered on-site on or after June 4, 2012. At this time, only beef manufacturing trimmings and not components (such as bench trim, or other components of ground beef such as cheek meat and head meat) are eligible for testing for non-O157 STEC, as well as E. coli O157:H7.3The Number Positive column on this table includes all samples that were positive for non-O157 STEC overall and does not reflect the total number of individual positive serogroups listed in the Non-O157 STEC (by serogroup) and E. coli O157:H7 table. This is due to the possibility that one sample may be positive for multiple serogroups.
